Safe interim storage and final disposal of radioactive waste (RW) requires effective characterization and quality control of the waste. The CHANCE project therefore aims to address the specific and complex issue of the characterization of conditioned radioactive waste (CRW) by means of non-destructive analytical (NDA) techniques and methodologies. Characterization issues within CHANCE encompass both physico-chemical characterization and radiological characterization.

The CHANCE project will establish a comprehensive understanding of current characterization methods and quality control schemes for conditioned radioactive waste in Europe. Furthermore, CHANCE will develop, test and validate already-identified and novel techniques that will undoubtedly improve the characterization of CRW. These techniques include:

  • Calorimetry as an innovative non-destructive technique to reduce uncertainties on the inventory of radionuclides;
  • Muon Tomography to address the specific issue of non-destructive control of the content of large volume nuclear waste;
  • Cavity Ring-Down Spectroscopy (CRDS) as an innovative technique to characterize outgassing of radioactive waste.

Finally, dissemination activities such as a Topical Day and a training course will be foreseen to share the project results with the stakeholders.


CHANCE project was presented in CHANCE and PREDIS workshops

The CHANCE project was presented in the EU-H2020 SHARE Decommissioning on-line workshop, which was held December 1-3, 2020, and in an on-line webinar of the EU-H2020 PREDIS Work Package 7 dealing with “Innovations in cemented waste package monitoring and storage” on January 19, 2021.

CHANCE project extended to December 2021

In order to cope with the impact of the covid-19 crisis, CHANCE launched an amendment with the European Commission to change the total duration of the Grant Agreement from 48 to 54 months. This amendment has been approved, meaning that the CHANCE project will now end at 2021-11-30.
